Manufacturer description

The MSI MAG A850GL PCIE5 is an 850W ATX power supply built for current-generation GPUs that pull hard, brief spikes through a single connector. It ships ATX 3.1 and PCIe 5.1 ready with a native dual-color 12V-2x6 cable, so you can run a modern graphics card without daisy-chaining adapters or stacking 8-pin splitters behind the motherboard tray. The 80 PLUS Gold certification keeps efficiency high under typical gaming loads, which means less waste heat inside the case and a quieter fan curve during long sessions. The fully modular design lets you connect only the cables your build actually…

Frequently Asked Questions

Is 850W enough for an RTX 5080 or similar high-end GPU build?

850W with ATX 3.1 and PCIe 5.1 support is sized for a single high-end GPU plus a mainstream CPU. Check your specific graphics card's recommended system wattage on its listing before buying.

Does it come with the 12V-2x6 connector, or do I need an adapter?

It includes a native dual-color 12V-2x6 cable, so no 8-pin-to-12VHPWR adapter is required for cards using that connector.

What warranty does MSI offer on this power supply?

MSI lists a 10-year limited warranty on the MAG A850GL PCIE5. Register and check the product listing for current terms in your region.
